Blew a Head Gasket

Update in the head gasket-

Well it blew and no it wasn't my fault cuz it was not really tuned. The place that put my block in, didn't really clean the head. By the looks of the head they grinded it down with those metal sanding things(brain fart, i forgot what the tool is called) and not all of it. They started and stoped. The guy showed were you can kinda the see the old gasket and the new gasket pressed together . My heads are getting resurfaced and there gonna check and the seals and crap. Any how, sadly the mechanic shop that did my work is gona ctch fire some how!!!!
